How to find your RAM speed, type, and size on Windows 10 and macOS

More people use computers than ever before, and yet the technicalities of hardware specifications remain a confusing minefield to many. 

One of the trickiest areas to make sense of can be your computer’s RAM. If you’re feeling overwhelmed by trying to decide what your computer’s stats mean, here’s a guide on how to find out your RAM speed, size, type, and more.

How to Find Out Your RAM Speed, Size, and Type in Windows 10

By far, the best method of finding out the details of your computer’s RAM is using the Windows 10 Command Prompt or Powershell. Other built-in applications like System Information and the Control Panel only show partial information like the size, type, or both. Here’s how to view extensive RAM details on your PC.

View RAM Information via Windows 10 Command Prompt

  1. Type “cmd” in Cortana’s search box and click on “Command Prompt” in the list.
  2. Type the following code into the command prompt and press enter:
    wmic MemoryChip get MemoryType, Name, Capacity, Configuredclockspeed, DeviceLocator, FormFactor, Manufacturer, Serialnumber, Speed
  3. For more advanced details, you can add other aliases:
    ConfiguredVoltage, DataWidth, MaxVoltage, CreationClassName, InterleavePosition. Note that some aliases may not show any information.
    To see all alias options, type the following and look under the “FULL” section:
    WMIC MemoryChip List /?

View RAM Information via Windows 10 Powershell

  1. Right-click the Windows 10 Start Menu and select “Powershell.” You don’t need to use admin privileges for this task.
  2. Type the following code into Powershell:
    Get-CimInstance -ClassName Win32_PhysicalMemory | Format-Table Capacity, Manufacturer, MemoryType, FormFactor, Name, Configuredclockspeed, Speed, Devicelocator, Serialnumber -AutoSize
  3. For a complete list of properties (Speed, Serial Number, FormFactor, etc.), visit the following page about Win32_PhysicalMemory Properties.

View Windows 10 Memory Details via CPU-Z

  1. Download CPU-Z and run the executable. You’ll most likely need the “Classic Versions” option.
  2. Navigate to the memory tab to view how many memory slots your PC has, installed memory type (DDR, DDR2, DDR3, etc.), and RAM size (GB). You’ll also see real-time information on the RAM’s running frequency plus a detailed breakdown of latency and clock speeds, should you require it.

How to Find Out Your RAM Speed, Size, and Type in macOS

  1. Step 1

    As with everything Apple, the process for finding basic details about your hardware is super-simple: just click the “Apple logo” and select “About This Mac.” Your simplistic RAM information gets displayed in the “Overview” tab.
  2. Step 2

    Should you be after a more in-depth report, a full technical breakdown is available by clicking “System Report” with your memory, processor, hard drive, and other components separated into tabs.

To view the real-time memory usage on your Mac running the latest software, use “Spotlight” to search for “Activity Monitor,” then click on the associated link to open it, and then select the “Memory” tab.

You can also access real-time memory information by opening “Finder,” clicking “Applications,” then selecting the “Utilities Folder,” followed by “Activity Monitor” and choosing the “Memory” tab.
